What will you do when your long time friend make use of you?

What will you do if your long time friend make use of you ?
I have one of such. At times I try to tolerate keeping in mind of the long term friendship.But at times I feel like telling her off. What you think is the best way ?

I think that it is unfair for her to do that. She knows you value the friendship and she is taking advantage of that by using you. Try not doing those things or using her instead, or just be very defensive and not get pushed around. It might get ugly, but the fact that it is a long term friendship, she probably won't hate you.
